Foreword by professor Carla Bruijnzeel-Koomen
Dear Colleagues and Friends,
We are proud to welcome you in the beautiful city of Utrecht.
It is a great honour for the eczema research community in the Netherlands to organize the 10th meeting of the
International Society of Atopic Dermatitis.
The Board of the ISAD has chosen Utrecht as the location for the 10th ISAD congress since the department of
Dermatology/Allergology in Utrecht has a longstanding focus on patient care and research in atopic dermatitis.
We hope you will enjoy the meeting in our charming University city with its characteristic houses and canals.
After decades of waiting for new drugs we recently entered an era with many promising new therapies, including
biologics and small molecules. The introduction of these drugs will have an enormous impact on the quality of life
of patients with moderate to severe atopic dermatitis. In addition, this will stimulate clinical and translational
research in atopic dermatitis. There are still many ‘research gaps’. Although we have made progress in the last
decades we still do not completely understand the clinical phenotypes with their comorbidities, we lack objective
disease parameters, and its genetics is still not understood. Furthermore, we need to study if the different clinical
phenotypes are related to different therapeutic strategies and also to primary prevention strategies.
We are very grateful for the large number of outstanding abstracts that we received for the 10th ISAD meeting.
Many important aspects of atopic dermatitis will be covered during the meeting. We are looking forward to
discuss your data and strategies to fill in the remaining gaps of knowledge.
We hope you will enjoy and become inspired by the ISAD meeting in Utrecht.
On behalf of the Local Organizing Committee

Short history of ISAD
The International Society of Atopic Dermatitis (ISAD) developed out of the tradition of the international atopic
dermatitis symposia created by the Hungarian dermatologist Georg Rajka in Oslo, starting back in 1979, when he
as an enthusiast for Atopic Dermatitis, would for the first time personally select and invite colleagues to a
conference on atopic dermatitis. The invitation always was “spiritual”, not financial in nature. He always also
invited younger colleagues, who would have done good work in the past three years to present in a forum of
experts in his chosen new homeland Norway. These meetings organized by George Rajka took place in Oslo
(1979 and 1982), Loen (1985), Holmenkollen (1989) and Lillehammer (1992), and virtually all people travelling to
Norway would take care of their own arrangements. It was in connection to one of those meetings, that the
classic and famous “Hanifin and Rajka criteria” for diagnosis of atopic dermatitis were born.
With the retirement of George Rajka, the meeting started to travel around the world, and different organizers
would add their specific touch to each meeting. We remember well the great meetings in Aarhus (1996)
organized by Kristian Thestrup-Pedersen, in Davos (1999) organized by Johannes Ring, when the name “Georg
Rajka Symposium” was added, in Portland (2001) organized by Jon Hanifin, in Rome (2003) organized by
Alberto Giannetti, in Archachon (2005) organized by Alain Taieb, in Kyoto (2008) organized by Masahiro
Takigawa, and in Munich (2010) organized again by Johannes Ring with the musical on King Ludwig II’s life,
death and allergy.
On the occasion of the 7th Georg Rajka International Symposium on Atopic Dermatitis in Moshi, Tanzania, in
January 2012, organized by John Mazenga and Peter Schmid-Grendelmeier, a motion was made to found an
International Society of Atopic Dermatitis which would organize future meetings, and also become active in
various aspects of Atopic Dermatitis at a global level. This idea was brought forward and led finally to the
founding of the International Society of Atopic Dermatitis in 2012. An alert bus driver can be thanked that the
majority of attendants escaped an armed attack on the bus during the way back to the hotel.
The founding meeting of the ISAD took place on the 7th of June, 2012, during the EADV Spring Meeting in
Verona in the Hotel Due Torri. In the early morning at 07:00 (!), Carlo Gelmetti (Milan), Amy Paller (Chicago),
Johannes Ring (Munich), Zsuzsanna Szalai (Budapest), the late Kristian Thestrup-Pedersen (Aarhus) and
Andreas Wollenberg (Munich) would meet in person for a working breakfast in close proximity to the famous St.
Anastasia church in Verona. Peter Schmid-Grendelmeier (Zurich) was present by phone. A board and an
executive committee were elected, and the basic rules for such a society would be discussed and agreed upon.
The other founding members were unable to attend the meeting in person.
The ISAD meeting 2014 in Nottingham organized by Hywel Williams stood under the auspices of Robin Hood
(with a short appearance of the Sheriff of Nottingham and the famous George Rajka song), and would emphasize
evidence based medicine, structured reviews in AD and hands-on experience in Ye Olde Trip to Jerusalem, one
of several pubs in England which claim to be the oldest.
The ISAD meeting 2016 in Sao Paulo organized by Roberto Takaoka had a focus on patient education and
clinical care with demonstration of live patients.
In the year of 2018, atopic dermatitis is the target disease of many new drug developments, but the microbiome,
biomarkers and genotype-phenotype correlations remain an important focus. We welcome all participants of the
2018 ISAD meeting in Utrecht, organized by Carla Bruijnzeel and Dirk Jan Hijnen, and hope that the spirit of the
first meetings dedicated to disease and patients will remain active in the beginning era of biologics entering the
field of Atopic Dermatitis.
